1 How parking guidance systems / car parking work
Firstly, UD takes use of ultrasonic wave to detect the car space to see if it is occupied by vehicles and transfer relative command to LED indicator which will turn from green to RED when occupied, or it will keep GREEN; Meanwhile, the UD transmit its status message to control unit immediately, and unit will collect and forward the information to CCU; CCU processes these data and sends the relevant command to unit and LED panel.
2 KEYTOP parking system / car parking advantages:
1) The technique of ultrasonic detector is steady and its anti-jamming capability is strong.
2) UD's accuracy rate is higher than loop sensor which has problem of weak magnetic and repeated detection. The base plate of UD is zoom type to avoid the problem causing by different setting angles without error accumulation.
3) UD has two detection methods, one is to detect the ground, the other is to detect the vehicles. Both of them are available for all kinds of car park's terrain.
4)The instruction's process chip and memory chip of UD has the function of storing different setting values(keep addresses setting and self-adapting setting,etc.), so it is unnecessary to reset after power-down.
5) The led indicator should be installed at every parking space to show the parking information to the drivers by its color(red when occupied, green when free). Long-distance control of led indicator is available by transmitting interrelated commands to UD. (The led indicator can be on or off regarding to different commands of UD, please note the UD manual for more details.) The color of led indicator is optional.
6) Using bus system with three-layer construction(CCU,unit,UD). So the structure is very simple and it's very easy to install and maintain. It also can operate without PC and will be influenced by PC problem.
7) The function of making a reservation, preventing occupancy, and anti-robery is available.
8) Base plate of UD: it can swing 15 degree to be installed forward and backward, so angle's variation improves its detection accuracy rate.
9) Network Wire Connection: Using the network wires to connect the components of PGS makes the installation easier and reduce much installation time and lower the connection error.
10) Energy Conservation Function: the led indicator will be on only when it's free, or it will be off, which will reduce 25% 33.3% of car park's energy charge.
